Households
Demand goods and services from the product market thereby help determine what gets produced
Supply the resources to resource markets thereby make what gets produced
When U.S. was an agricultural economy, a farm household was largely self-sufficient they produced what they consumed and consumed what they produced
![Page 3: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/3.jpg)

Households
Shifts from agricultural economy to industrial economy Improved farm productivity Growth of urban factories Increase in number of women in work force Rise of two earner families Increased opportunity cost of working at home Advantages of specialization in household of
declined
![Page 4: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/4.jpg)

Households Maximize Utility
People are assumed to try and maximize their level of satisfaction, sense of well being, or overall welfare utility Rational: act in the best interest of the household
Use their limited resources to satisfy their unlimited wants
![Page 5: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/5.jpg)

Households as Resource Suppliers
Over two-thirds of personal income comes from labor earnings
Certain individuals receive assistance from the government in the form of transfer payments: cash or in-kind benefits given to individuals as outright grants from the government Cash transfers are monetary payments: welfare
benefits, unemployment compensation, etc. In-kind transfers provide specific goods and services:
food stamps, Medicare, and Medicaid are all examples of in-kind transfers
![Page 6: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/6.jpg)

Exhibit 3-1(a) Nearly two-thirds of personal income in 2003 was labor income
63%
![Page 7: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/7.jpg)

Households as Demanders of Goods and Services
Personal income 81 percent for personal consumption 3 percent is saved 16 percent goes for taxes
Categories of spending Durable goods: last three or more years Nondurable goods: food, clothing Services: haircuts, medical care
![Page 8: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/8.jpg)

The Evolution of the Firm
Individual consumer could undertake the process of negotiating with all the necessary parties to produce a particular product Transaction costs could easily erase the gains from
specialization Behooves the individual consumer to pay someone
to undertake all these tasks Entrepreneur who organizes the production process
and reduces transaction costs Cottage industry putting out raw materials
![Page 10: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/10.jpg)
10
The Evolution of the Firm
Combination of technological advances, increased worker productivity led to shift of employment from rural to urban areas
Work became organized in large, centrally powered factories that Promoted a more efficient division of labor Allowed for the direct supervision of production Reduced transportation costs Facilitated the use of machines far bigger than
anything that had been used in the homeIndustrial Revolution
![Page 11: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/11.jpg)
11
The Evolution of the Firm
Firms are economic units formed by profit-seeking entrepreneurs who combine the resources to produce goods and servicesWe assume firms attempt to maximize
profits entrepreneur’s reward = revenue minus cost of production
![Page 12: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/12.jpg)

14
Sole Proprietorship
Advantages Simplest Single owner who has the right to all profits –
complete controlDisadvantages
Unlimited liability for any business debts and can in fact lose personal assets
Goes out of business upon the death of the proprietor
Limited ability to raise capital
![Page 15: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/15.jpg)
15
Partnership
Multiple owners who share the firms profitsCommonplace in law, accounting, and medical
practiceAdvantage: Often easier to raise sufficient
funds to get the business going than with a sole proprietorship
Disadvantages: Each partner usually faces unlimited liability for all
the the debts and claims against the partnership The death or departure of one partner may force
costly reorganization
![Page 16: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/16.jpg)
16
Corporation
Legal entity owned by stockholders
Advantages First, and most important is that this is the easiest
way to raise capital funds Second, stockholders have limited liability their
liability for any losses is limited to the value of their stock
Third, corporation has a life apart from its owners
![Page 17: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/17.jpg)
17
Corporation
DisadvantagesStockholder’s ability to influence corporate
policy is limited to voting for a board of directors
Corporate income is taxed twice: first as corporate profits and second as stockholder income, either as corporate dividends or as realized capital gainsRealized capital gain is any increase in the
market value of a share that occurs between the time the share is purchased and the time it is sold
![Page 18: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/18.jpg)
18
Subchapter S Corporations and Nonprofit Organizations
Subchapter S corporation Hybrid that takes advantage of the limited liability
feature of the corporate structure but has the Income is only taxed once as profits Limited to no more than 35 stockholders
Nonprofit Organizations Do not have profit as explicit objective Have to generate enough revenue to pay bills Non-taxpaying entities
![Page 19: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/19.jpg)

Why Does Some Household Production Still Exist?
No skills or specialized resources requiredHousehold production avoids taxes
Tax free nature of do it yourself activity favors household production over market transactions
Reduces transaction costsVarious technological advances have
increased household productivity
![Page 20: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/20.jpg)

Role of Government
Role of Government Establishing and enforcing the rules of the game Promoting competition Regulating natural monopolies Providing public goods Dealing with externalities More equal distribution of income Full employment, price stability, and economic
growth
![Page 21: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/21.jpg)

Exhibit 3: Redistribution has Grown and Defense has Declined
![Page 22: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/22.jpg)
22
The Rules Of The Game
Efficiency depends on individual confidence that they can use the resources they own to maximize their utility
Governments Safeguarding private property Enforce contracts through the judicial system
Market participants play by the “rules of the game” as set forth by the participants through laws, customs and conventions
![Page 23: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/23.jpg)
23
Promoting Competition
Although the “invisible hand” of competition usually promotes an efficient allocation of resources, it is reasonable to believe that some firms try to avoid competition through collusion
Government antitrust laws try to promote competition by prohibiting collusion and other anticompetitive practices
![Page 24: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/24.jpg)
24
Regulating Natural Monopolies
Monopoly is a sole producer of a product for which there are no close substitutes
In some instances a monopoly can produce and sell the product for less than could several competing firms
Natural monopoly One firm that can serve the entire market at a lower
per- unit cost than can two or more firms Maximizes profit by charging a price higher than is
optimal from society’s point of view government usually regulates these firms
![Page 25: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/25.jpg)
25
Providing Public Goods
Private goods Rival in consumption: the amount consumed by one
person is unavailable for others to consumer Suppliers can easily exclude those who fail to pay –
private goods are exclusivePublic goods
Nonrival in consumption: one person’s consumption does not diminish the amount available to others
Nonexclusive: sellers cannot easily exclude nonpayers Government uses taxing power to finance these goods National Defense and Judicial System are good examples
![Page 26: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/26.jpg)
26
Dealing With Externalities
Market prices reflect the private costs and benefits of producers and consumers
Externality is a cost or benefit that falls on third parties and is therefore ignored by the two parties to the market transaction Negative externality imposes a cost on third parties
– pollution, jet noise, and auto emissions are all good examples of negative externalities
Positive externality confers benefits on third parties – inoculations and education are goods that are felt to convey positive externalities
![Page 27: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/27.jpg)
27
A More Equal Distribution Of Income
Resource markets do not guarantee each household even a minimum level of income
Transfer payments reflect in an society’s attempt to provide a basic standard of living to all individuals
Key Issues How much should be redistributed? What form should it take? Who should receive the benefits? How long should the benefits continue?
![Page 28: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/28.jpg)
28
Full Employment, Price Stability, And Economic Growth
Fiscal policy refers to the use of government purchases, transfer payments, taxes, and borrowing to influence aggregate economic activity
Monetary policy refers to regulation of the money supply in order to influence aggregate economic activity
![Page 29: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/29.jpg)
29
Government’s Structure and Objectives
Federal system of government: shared responsibilities Federal government has assumed primary
responsibility for national security and the stability of the economy
State government for public higher education, prisons, and with aid from the federal government, highways and welfare
Local government responsibilities include primary and secondary education, police and fire protection
![Page 30: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/30.jpg)
30
Defining Government Objectives
What do government decision makers attempt to maximize?
Problems 87,000 separate jurisdictions Separation of powers between the executive, legislative,
and judicial branches: no single, consistent decision maker
Agencies and bureaus may work at cross purposes
Elected officials try to maximize the probability of getting elected
![Page 31: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/31.jpg)
31
Voluntary Exchange Versus Coercion
Biggest difference between government and the market is that the market relies on the VOLUNTARY behavior of buyers and sellers
Conversely, by its very nature, any voting rule and any governmental body involves or employs some element of coercion
![Page 32: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/32.jpg)
32
No Market Prices
Selling price of public output is usually either zero or some amount below its cost
Because the revenue side of the government budget is separate from the expenditure side, no necessary link between the cost and benefit of a public program or good
In the private sector, marginal benefits are at least equal to marginal costs
![Page 33: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/33.jpg)
33
Size and Growth of Government
Comparison of government spending to gross domestic product, or GDP GDP is the total value of all final goods and services
produced in the United States In 1929, the year the Great Depression began,
government spending, mostly by state and local governments, totaled about 10% of GDP
By 2004 government outlays were 36% of GDP 38% in Japan, the United Kingdom, and Canada,
43% in Germany, 47% in Italy, 51% in France
![Page 34: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/34.jpg)
34
Sources of Government Revenue
Taxes are largest source of revenue at all levels of government
Largest source for Federal government is individual income tax
State governments rely on income and sales taxes
Local government rely on the property tax
![Page 35: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/35.jpg)

Exhibit 4: Payroll Taxes Have Grown as a Share of Federal Revenue
![Page 36: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/36.jpg)
36
Tax Principles
Structure of a tax system is based on one of two general principles
Ability-to-pay principle based on premise that those with a greater ability to pay should pay more tax
Benefits-received tax principle based on premise that those who receive more benefits from the government program funded by a tax should pay more tax
![Page 37: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/37.jpg)
37
Tax Incidence
Tax incidence indicates who actually bears the burden of a tax
Most common way of evaluating tax incidence is by measuring the tax as a percentage of income Proportional taxation Progressive taxation Regressive taxation
![Page 38: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/38.jpg)
38
Tax Incidence
Proportional tax Taxpayers at all income levels pay the same
percentage of their income in taxes Also called a flat tax since the tax as a percentage of
income remains constant as income changesProgressive
The percentage of income paid in taxes increases as income increases
Regressive The percentage of income paid in taxes decreases as
income increases
![Page 39: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/39.jpg)
39
Marginal Tax Rate
Marginal tax rate measures the percentage of each additional dollar of income, assuming this is the appropriate base, that is paid as taxes
MTR = Δ Tax Liability / Δ Income
Key here is that high marginal tax rates reduce the after tax return from working or investing – incentives to work or invest are reduced
![Page 40: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/40.jpg)

Rest of the World
International trade arises for the same reason as individual trade the opportunity cost of producing specific goods differ among countries
International trade is becoming an increasingly large force in the U.S. economy Exports have doubled since 1970 Largest customers are Canada, Japan, Mexico,
Great Britain, Germany, France, South Korea & Taiwan
![Page 42: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/42.jpg)
42
Rest of the World
Merchandise trade balance = the value of a country’s exported goods minus the value of its imported goods during a given time period Distinguishes between goods and services U.S. has experienced a merchandise trade deficit:
the value of goods imported has exceeded the value of goods exported
Deficit must be offset by a surplus in one or more of the other balance-of-payments accounts
Balance of payments Record of all economic transactions between
residents of one country and residents of the rest of the world during a given time period
![Page 43: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/43.jpg)
43
Exchange Rates
Lack of a common currency complicates trade between countries a market for foreign exchange has developed
Foreign exchange is a foreign currency needed to carry out international transactions Supply and demand for foreign exchange determine
the equilibrium exchange rate between two countries
Exchange rate measures the price of one currency in terms of another
![Page 44: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/44.jpg)
44
Exchange Rates
For example, the exchange rate between the euro and the dollar might indicate that one euro exchanges for $1.10 At this exchange rate, a Porsche selling for 100,000
euros would cost an American consumer $110,000
Exchange rate affects the prices of imports and exports and helps shape the flow of foreign trade The greater the demand for a particular foreign
currency or the smaller its supply, the higher its exchange rate
![Page 45: 1 Economic Decision Makers Chapter 3 © 2006 Thomson/South-Western.](https://reader035.fdocuments.us/reader035/viewer/2022081603/56649de65503460f94aded93/html5/thumbnails/45.jpg)
45
Trade Restrictions
Nearly all countries impose restrictions of this flow of goods and services
These restrictions can take one of three formsTariffs which is a tax on imports or exportsQuotas are legal limits on the quantity of a
particular good that can be importedVoluntary agreements
